Welcome to the world of Objects and Friends! Today, we’re going to learn about something super cool in programming called “objects.” Many programming languages, like Python, Java, and CoffeeScript, use objects to make coding easier and more fun. In a game like Code Monkey, objects are the characters you see on the screen. Because CoffeeScript is object-oriented, you can use these objects in your code to make things happen!
Let’s dive into an example. Imagine you’re playing a game with lots of characters on the screen. You can find out which characters are objects by moving your mouse over them. If a name pops up, it means that character is an object you can use in your code. For instance, in our game, the monkey, the turtle, the bananas, and the bushes are all objects. But some things, like the ruler and Gordy, are not objects.
Now, let’s see how we can solve a challenge using objects. Our goal is to help the monkey get an apple and some bananas from a stream. To do this, the monkey needs to get on the turtle, have the turtle move across the river, and then grab the bananas.
Here’s how we can do it:
In object-oriented programming, objects are like the stars of the show. They can do things and interact with each other in your code. By using objects, you can make your programs more organized and easier to understand.
Now that you know how objects work, it’s your turn to use them in your code. Remember, objects can be anything from characters to items in a game. Have fun experimenting and see what you can create!
Good luck, and happy coding!
Explore a simple game or interactive website and identify objects by hovering over them. Write down the names of the objects you find and discuss how they might be used in a program.
Create a simple scene using a block-based coding platform like Scratch. Use different sprites as objects and write code to make them interact, such as moving or changing appearance.
Write a short story where each character or item is an object. Describe what actions they can perform and how they interact with each other. Share your story with the class.
Draw a picture of a scene from a game or story. Label each part of the drawing as an object and describe what actions it can perform in a program.
Solve a puzzle by writing simple code to make objects interact. Use a platform like Code.org or Tynker to practice using commands that control objects in a virtual environment.

[Music] Welcome to Objects and Friends! Let’s learn about objects. Many programming languages are object-oriented, including Python, Java, and our very own CoffeeScript. In Code Monkey, objects are the characters on the screen. Because CoffeeScript is object-oriented, you can use those objects in your code.
Let’s look at an example. Here’s a challenge that has several characters on the screen. You can tell which characters are objects by hovering your mouse over them; if a name pops up, it means it’s an object that you can use in your code.
For example, the monkey got the turtle, both bananas, and all these bushes. But is the ruler an object? No, and Gordy isn’t one either. However, all these other images are objects.
Now, let’s see how we would solve this challenge. We want the monkey to get the apple in the stream, as well as the banana in the stream and this banana. So, the monkey will have to somehow get on the turtle, have the turtle move across the river, and then go and get this banana as well.
What we could do is use the command “turn to.” We could turn to any object; for instance, I could turn to one of these bushes, but I think I want to turn to the turtle. So, I will say “turn to,” and because this is an object-oriented program, I could just say “turtle,” and then I could step.
I don’t need to mention the monkey in my code because, since the monkey is the main character of the challenge, it will automatically do the step and the turn to will automatically refer to the monkey. However, if we want the turtle to step, I’d have to mention the turtle.
So right now, we’re going to have the monkey step 10. Let’s run that. Okay, so now the monkey is on the turtle. Next, we want the turtle to step. Since we want the turtle to step, I actually have to say “turtle step.” Let’s see how far it is. I think it’s 15.
So, it’s actually “turtle.step(15).” Okay, let’s run that. We’re all lined up. I could have the monkey turn to the banana object, but they’re saying I could just walk backwards, which would require less code, so let’s do that.
Do you remember how to make the monkey walk backwards? Yes, you use a negative number. Okay, let’s run one more time.
Hopefully, that explains how different characters are objects and how you can use them in your code. Now it’s your turn to use objects. Good luck!

Objects – In coding, objects are things that can hold data and perform actions. – In the game, the car and the tree are objects that the player can interact with.
Coding – Coding is the process of writing instructions for computers to follow. – We spent the afternoon coding a simple game where a cat chases a mouse.
Programming – Programming is creating a set of instructions that tell a computer how to perform a task. – Programming can be fun when you see your robot follow the path you designed.
Python – Python is a popular programming language known for being easy to read and use. – We used Python to create a program that tells jokes.
Java – Java is a programming language used to build many types of applications. – My brother is learning Java to make an app for his phone.
Turtle – In coding, a turtle is a tool used to draw shapes and designs on the screen. – We used the turtle in Python to draw a colorful star.
Monkey – In some coding games, a monkey can be a character that players control or interact with. – The monkey in the game collects bananas as it jumps from tree to tree.
Bananas – In coding games, bananas can be items that characters collect for points. – Each time the monkey grabs bananas, the player earns extra points.
Challenge – A challenge in coding is a problem or task that tests your skills. – The challenge was to code a maze that the robot could solve on its own.
Game – A game is a program designed for fun and entertainment, often involving challenges or goals. – We created a game where players have to solve puzzles to rescue a lost puppy.
